I just want to be honest with you folks, and be as realistic with you as possible. Changes to the Alien Blue app happen in 6-9 month intervals. Regardless of NP's popularity, it would most likely take quite a bit of time to implement this functionality since changes are rolled out in large updates over the span of many months.

Additionally, Alien Blue for iPhone and Alien Blue for iPad are two separate apps with similar, but different code. It is not a universal app. The apps are both on different update schedules that are typically 1-3 months apart. If NoParticipation is added to the iPhone version of the app it would take more time for it to be implemented on iPad version.

I just wanted to tell you this in order to set realistic expectations.

Does AlienBlue support links to other locales (es.reddit.com, fr.reddit.com, etc.?) If not, you may have better luck lobbying for locale support than for NP support specifically. I think it would be fair to call that a bug, not a missing feature.
